Impact
Cleartext transmission is used for certain cluster‑management communications in Progress MarkLogic Server 12.x releases prior to 12.1.0. This flaw allows an attacker positioned on the same network to intercept, read, or modify data exchanged during cluster join operations, potentially leading to unauthorized alteration of cluster configuration or execution of malicious commands. The weakness is represented by CWE‑319.
Affected Systems
The vulnerability affects Progress Software Corporation’s MarkLogic Server 12.x series on all releases earlier than 12.1.0. Versions 12.1.0 and later have been updated to use encrypted transport for cluster‑manager communications, eliminating the exposure.
Risk and Exploitability
The CVSS score of 7.4 indicates a high‑impact vulnerability, and while the EPSS score is not provided, the absence of a public exploit does not reduce the risk for a network‑positioned attacker who can observe or tamper with traffic between cluster nodes. The vulnerability is not yet listed in the CISA KEV catalog, but the potential for data integrity compromise warrants precautionary measures.
